Pituitary Gland
The pituitary gland is no larger than the size of a pea. It was once called the "master gland" of the body because its hormones control the function
of other endocrine glands. The hypothalmus is really a master gland inbetween the brain and the pituitary gland. The hypothalmus controls the pituitary gland.
The pituitary gland's hormones affect growth, sexual development, metabolism and the system of reproduction. The gland consists of two lobes which release
different hormones. The "anterior lobe" releases about six important hormones. These include:
growth hormone (GH) - stimulates the growth of muscles and bones
prolactin - stimulates production of milk in the breasts after giving birth
thyroid-stimulating hormone (TSH) - stimulates the thyroid gland to produce thyroxine
follicle-stimulating hormone (FSH) - stimulates production of testosterone in males and helps in the development of male and female gametes
adrenocorticotropic hormone (ACHT) - stimulates the adrenal glands to produce steroid hormones
luteinizing hormone (LH) - stimulates the ovaries or testes
The "posterior lobe" produces these hormones:
antidiuretic hormone (ADH) - stimulates the increase of absorption of water into the blood by the kidneys
oxytocin - stimulates the contraction of the uterus during childbirth and stimulates milk production
